Hierarchy v2: Undo operation fails to preserve the expanded state of a moved node, causing it to collapse instead of maintaining its original expanded state.

Steps to reproduce:

1. Create a node with children
2. Expand this node
3. Move the expanded node to an existing node as a child and then undo 

Actual results: The expanded node is now collapsed, undo shouldn't reset its previous expanded state

Expected results: undo doesn't reset its previous expanded state

Reproducible with versions: 6000.5

Not reproducible with versions: 

Can’t test with versions: latest 6000.4(a5) and 6000.3

Tested on (OS): Mac
